Re: 3rd layer of gum
P.S. My experience doesn't support the idea suggested somewhere in this thread that the more soakings of the paper, the smoother and more closed the fibers will get with the increased shrinking; my experience suggests just the opposite, that with every soaking of the paper, the paper becomes more open and coarse. In fact that's one of many reasons why I like my present paper (Arches bright white) so much, in spite of its challenges: it is the *only* hot press paper I've found that keeps its smooth crisp surface over several soakings rather than becoming more and more coarse and textured.

Paul, I've only seen this with nonabsorbent surfaces like glass and yupo, and only in areas where there are actually three layers of hardened gum. (for instance if there's an area that's all blue, where little or no yellow or red pigment have been deposited, there's no problem with adherence of the third (blue) layer, only in more neutral and mixed areas where there are equal amounts of all gum layers. I've never seen it with paper.
